Ethereum Ecosystem — 2026-05-20
The Ethereum Foundation continues to face a significant wave of researcher departures, with two more exits announced this week, compounding organizational uncertainty at a critical juncture. Meanwhile, a fresh $11 million DeFi exploit on the Verus Protocol adds to ongoing security concerns across the ecosystem. ETH price remains under pressure, hovering just above $2,100 as governance turbulence and security incidents weigh on market sentiment.

Ethereum Foundation Exodus Continues as Researchers Carl Beek and Julian Ma Depart
The Ethereum Foundation is facing an accelerating wave of high-profile departures, with researchers Carl Beek and Julian Ma announcing their resignations this week — the latest exits in what has become a sustained organizational shakeup. The turnover comes as the foundation undergoes an internal transition tied to a new organizational mandate aimed at redefining its role within the broader Ethereum ecosystem.
According to reporting from The Block and CoinDesk, the string of departures represents a broader shakeup that has seen several core members leave in just a few months, further dampening community morale — particularly amid ETH's relatively weak price performance. The Ethereum Foundation is in the midst of redefining what its role should be as the protocol matures and more development activity shifts to independent teams and Layer 2 ecosystems.
The significance of these departures extends beyond personnel: research continuity is critical as Ethereum navigates a complex upgrade roadmap that includes the Glamsterdam and Hegota upgrades, FOCIL (Fork-choice enforced Inclusion Lists for censorship resistance), and post-quantum cryptography planning. Losing experienced researchers mid-cycle could slow progress on these fronts, though the open-source nature of Ethereum development means contributions can continue from outside the foundation.
Community observers note that the foundation's restructuring, while disruptive in the short term, may ultimately lead to a more decentralized model for Ethereum's ongoing development — aligning with its long-stated goal of reducing dependence on any single entity.
Protocol & Development
-
Vitalik Buterin on AI-Assisted Formal Verification: Ethereum co-founder Vitalik Buterin published views this week arguing that combining AI with formal verification could represent the "final form" of software development — and a critical security tool for crypto networks. Buterin specifically highlighted how mathematically verified software running on the raw EVM, combined with tools like Lean, could eliminate classes of critical bugs in high-security code. This matters for Ethereum because the protocol's smart contract layer remains a primary attack surface for exploits.

Ethereum Foundation Internal Restructuring Deepens: PANews reports that in just a few months, the Ethereum Foundation has lost several veteran leaders, with the latest departures (Carl Beek and Julian Ma) further signaling a structural transition. The organization is working through a mandate shift intended to clarify EF's role as Ethereum becomes more self-sufficient — though the timing, amid a weak ETH price environment, has unsettled parts of the community.

L2 Scaling Activity Metrics: According to L2BEAT data, Ethereum Layer 2 rollups recorded approximately 1,350 user operations per second (UOPS) in the past day, representing a 48.53x scaling factor over Ethereum mainnet's ~21 UOPS. This underscores the extent to which L2s have become the primary transaction layer for the Ethereum ecosystem — a dynamic that reshapes how base layer security, fee revenue, and upgrade priorities are evaluated.
DeFi Pulse
- Total Ethereum DeFi TVL: DefiLlama tracks Ethereum as the dominant DeFi chain; specific 24-hour TVL figures require direct verification at defillama.com/chain/ethereum.
- Top Movers: Aave V3 on Ethereum remains one of the largest protocols by TVL at approximately $14.6 billion, per DefiLlama's Aave protocol page.
- Verus DeFi Protocol Exploit — $11M Drained: A fresh exploit targeting the Verus DeFi protocol drained approximately $11 million, adding to a string of DeFi security incidents in 2026. The attack has contributed to bearish price pressure on ETH, which is holding just above the $2,100 level. Details on the exploit vector have not yet been fully disclosed, though Cryptonews reports the incident has reinforced near-term bearish predictions for Ethereum's price.
Layer 2 & Scaling
-
L2 Ecosystem Activity at Record Scaling Factor: L2BEAT data shows Ethereum's rollup ecosystem is operating at a 48.53x scaling factor versus mainnet, with rollups collectively processing ~1,350 UOPS versus Ethereum's ~21 UOPS. Arbitrum maintains its position as the leading Stage 1 Optimistic Rollup, with non-emergency upgrades subject to an 8-day delay on L2 and a 3-day delay on L1, providing meaningful user protection windows.
-
L2 Security Stage Rankings in Focus: The SpotedCrypto L2 Scorecard for mid-2026 compares Arbitrum, Base, OP Mainnet, zkSync Era, and others across TVL, fees, TPS, and L2Beat security stage ratings. Security stage ratings — which assess how much user protection each rollup provides against malicious or buggy upgrades — remain a key differentiator for DeFi users choosing where to deploy capital. Arbitrum leads on security stage maturity among major rollups.
-
Ethereum Optimistic Rollups Technical Documentation Updated: Ethereum.org's developer documentation on optimistic rollups was updated in late February 2026, noting that blob-based data posting (introduced via EIP-4844) allows rollups to significantly reduce L1 costs. Blobs are pruned after approximately 18 days (~4,096 epochs), keeping them affordable while maintaining the security window needed for fraud proof challenges.
What to Watch
- Ethereum Foundation restructuring: Monitor whether additional senior departures occur in the coming days and how the organization's new mandate takes shape. Key question: does the restructuring accelerate or slow the Glamsterdam and Hegota upgrade timelines?
- Verus exploit fallout: Watch for post-mortem analysis of the $11M Verus DeFi exploit and any governance response from the protocol. Similar exploits have triggered broader DeFi risk-off sentiment in the past.
- ETH price support at $2,100: With the EF governance uncertainty and fresh security incidents, ETH is testing a key psychological support level. A sustained break below could signal further weakness.
- Vitalik's AI + formal verification push: Buterin's call for EVM-based formal verification could catalyze new tooling and research efforts. Watch for follow-up proposals or EIPs referencing these ideas, particularly around smart contract security auditing.
Reader Action Items
- DeFi security review: Given the $11M Verus exploit, this is a good moment to audit your DeFi positions — particularly in newer or smaller protocols. Review whether your protocols have completed formal audits and what their upgrade governance looks like.
- L2 selection for yield: If you're optimizing for both security and yield, the mid-2026 L2 scorecard suggests prioritizing protocols on Arbitrum (Stage 1, strong security rating) or Base for established DeFi strategies, while treating lower-stage rollups as higher-risk environments.
- Governance monitoring: Ethereum Foundation departures may create temporary gaps in key research areas. If you hold ETH or participate in Ethereum-adjacent governance (e.g., Aave, Uniswap), keep an eye on how protocol teams respond to any slowdown in core EF research output.
